文摘
- •
The chlorophyll removal mechanism of Ambersep 900 OH was studied with LC-PDA–am-MS.
- •
Chlorophyll removal is not caused by apolar adsorption, hydrolysis or anion exchange.
- •
Chlorophyll is most probably adsorbed by H-bonds and dipole–dipole interactions.
- •
Chlorophyll removal with the strong basic resin is therefore very selective.
- •
The natural composition of esterified compounds (e.g. carotenoid esters) is preserved.
